Design and additive manufacturing of devices for orthotics and prosthetics

A presentation by Helda Pahlavani, Faculty of 3mE, Mechanical, Maritime and Materials Engineering, Delft University of Technology.

The patient-specific (PS) design of prosthetics and orthotics is a common approach to design various medical devices (e.g., transtibial sockets). Such PS designs are based on the patient’s anatomy obtained from different medical imaging modalities thus allowing for better fixation and improving the patient’s comforts and enabling successful rehabilitation.

The emergence of additive manufacturing (AM) makes the high-quality manufacturing of these complex PS medical devices more feasible. Moreover, the functionality of the designed medical device subjected to various physiological loading scenarios can be evaluated by computational models. These computational models can also provide further insights into the structural, topology, and material optimization of PS medical devices.

Here we developed a workflow connecting between different steps in the design of PS prosthetics and orthotics including imaging, computational modeling, optimization, and rapid prototyping using AM.

Question 1: What drives you?
My motivation is to help patients and improve the quality of their life by designing functional and innovative medical devices.

Question 2: Why should the delegate attend your presentation?
This presentation would be interesting for people who want to know more about new techniques of design and manufacturing of personalized medical devices.

Question 3: What emerging technologies/trends do you see as having the greatest potential in the short and long run?
Mechanical metamaterials have great potential to introduce novel designs since they are able to provide contradictory design requirements.

Question 4: What kind of impact do you expect them to have?
Improvement of functionality and comfort of medical devices

Question 5: What are the barriers that might stand in the way?
Challenging manufacturing because of the complex geometry
